2 Timothy 3:14-15

But continue thou in the things which thou hast learned That is, continue to believe and obey them; and hast been assured of Namely, of their absolute certainty and infinite importance; knowing of whom thou hast learned them And what convincing evidence I have given thee that I have been commissioned by God to attest and teach them. And that from a child Απο βρεφους, from an infant; thou hast known the Holy Scriptures Of the Old Testament, which only were extant when Timothy was an infant. The apostle calls them holy or sacred Scriptures, or writings, because they were given by inspiration of the Holy Ghost, through the instrumentality of holy men, because they treat on holy things, contain holy doctrines, precepts, and promises, and are designed and calculated to make people holy. It must be remembered, that Timothy's mother and grandmother, being pious Jewish women, had trained him up from his childhood in the knowledge and belief of the writings of Moses and the prophets. And their care in thus instructing him, being commended by the apostle, shows us that little children ought to be made acquainted with the Scriptures as early as possible; and that they may derive much benefit even from that imperfect knowledge of them, and of the principles of religion, which they are capable of attaining in their tenderest years. Which are able to make thee wise unto salvation Even the Scriptures of the Old Testament were able to make men thus wise, through faith in the Messiah, before he came. How much more are those of the Old and New Testaments, taken together, able, in God's hand, to make us more abundantly wise unto salvation, through faith in him actually come, even such a salvation as was not known before Jesus was glorified? See 1 Peter 1:10.
